This is using MS Exchange 2007 server. Whenever I tried to send a mail to abc.com, the mail failed. I can see that the mail is stuck in the Exchange Queue. From Queue viewer, I found this mail with following status:

   450 4.5.0 No recipient succeeded

All other domains are ok. Why? How to troubleshoot?

Thanks in advance!
